Peephole LSTM

Closed weights IDSIA 0K parameters July 2000

No estimate

No hardware requirements for this model

The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean

What this model is

Peephole LSTM was published by IDSIA, in Switzerland, in July 2000. academia is the category the publisher falls under.

It works in Mathematics, and is recorded as doing periodic function approximation.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Answers

Peephole LSTM — common questions

01

Is Peephole LSTM open source?

The licensing for Peephole LSTM was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

02

How many parameters does Peephole LSTM have?

Peephole LSTM has 0K parameters. "In absence of the 3 peephole connections there are 14 adjustable weights". That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

03

Who created Peephole LSTM?

Peephole LSTM was published by IDSIA, based in Switzerland, categorised as academia.

04

When was Peephole LSTM released?

Peephole LSTM was published in July 2000. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

What is Peephole LSTM used for?

Peephole LSTM works in Mathematics, and is recorded as handling periodic function approximation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

What GPU do I need to run Peephole LSTM?

None. Peephole LSTM is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.

Looking at it from the other side?

This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
